Executive summary
This deliverable describes the barriers and success factors to successfully co-create nature-based
solutions (NBS). The potential positive interactions of environmental, economic and social systems lie at
the heart of NBS. The interventions planned within the CLEVER Cities projects therefore embrace the
concept of NBS. Such a comprehensive approach, however, causes special technical, economic, financial
political and social challenges for the successful implementation of the envisioned interventions.
The factsheet draws on the experiences of past and ongoing projects in the field of nature-based solutions
and urban regeneration. Evidence was gathered not only from sources explicitly focused on nature-based
solutions, but also from those dealing with the related topics of urban regeneration, ecosystem services,
green (and blue) infrastructure and climate adaption in cities more broadly.
Ten key barriers were identified through the review and include: the limited knowledge base for nature-
based solutions; the inadequate governance structures for NBS; the balancing of the multiple goals NBS
can deliver; effective citizen involvement; insufficient social inclusion and social acceptance; lack of political
and financial support; the challenges for monitoring NBS; and, the difficulties in upscaling NBS.
The presented solutions to these challenges show that the interactions of environmental, economic and
social systems have to be considered at all stages of co-creation, implementation, evaluation and upscaling.

1. Introduction
1.1. Objective
This factsheet identifies ten common barriers to the effective co-creation, implementation, evaluation and
upscaling of nature-based solutions (NBS); it also highlights potential success factors for overcoming these,
which can be applied in the CLEVER Cities project. The findings are intended to guide related activities
taking place in the project’s front-runner and fellow cities.
1.2. Context and approach
While the term ‘nature-based solutions’ has only emerged in recent years, the idea of utilising nature as a
tool to address a range of urban challenges while also supporting resilient, sustainable and inclusive city
development has a far more established history. The European Commission is amongst those advocating
for the use of such solutions1 and has financed various projects to research and implement NBS, not least
in the field of urban regeneration.2 CLEVER Cities is itself such a European Commission funded project
and recognizes the value of knowledge and experiences emerging out of related research and practical
implementation endeavors.
This factsheet focuses its research on the experiences of NBS-related projects funded and delivered in
recent years by the Commission and its partners, and has identified the barriers and success factors that
need to be understood to ensure to more successful co-creation and implementation of NBS in cities (a full
list of consulted and further projects of relevance are listed in Annex 1). Published literature from these
projects, as well as other scientific and grey literature plus the experience of CLEVER Cities project partners
has informed the research. Evidence was gathered not only from sources explicitly focused on nature-
based solutions, but also from those dealing with the related topics of urban regeneration, ecosystem
services, green (and blue) infrastructure and climate adaption in cities more broadly.
2. Key barriers to successful
implementation of NBS and
factors for improving success
Key barriers that were identified through the review include: the limited knowledge base for nature-based
solutions; the inadequate governance structures for NBS; the balancing of the multiple goals NBS can
deliver; effective citizen involvement; insufficient social inclusion and social acceptance; lack of political and
financial support; the challenges for monitoring NBS; and, the difficulties in upscaling NBS. The following

subchapters explain these barriers in more detail and describe possible solutions and success factors. In
addition, the table in Annex 2 offers an overview of the identified barriers and success factors.
2.1. Knowledge gaps
Successful implementation of NBS is largely dependent on having sufficient scientific and technological
knowledge of their function performance and benefits. This includes having a solid understanding of the
complex processes of natural systems, as well as the appropriate NBS design features and options in order
to ensure that the solutions are resource-efficient, resilient to change, and adapted to local conditions (1).
Even though there is a growing body of knowledge and experience of NBS, information is often scattered
and hard to access (2).3 Moreover, existing evidence is often presented in such a way that is challenging
for policy and decision-makers as well as the general public to understand, and frequently not in a ‘ready-
to-apply’ format, or tailored to the specific local challenge (3).4 More awareness of the potential business
opportunities offered by NBS in cities is also needed as the implementation of NBS can be constrained by
the lack of high-performing private companies operating in the field of urban forestry, sustainable drainage
and landscape management.5 The limited numbers of firms available to implement innovative NBS can also
complicate public tendering processes (4).
One solution to close the knowledge gap within city departments is to identify, integrate and utilise the
capacity of local stakeholders in the project design and delivery, including the qualified technical staff,
engineers and landscape architects employed by or available to these local stakeholders (2,5,6,7). In
addition, staff from city departments such as planning, highways or parks management can attend bespoke
education and training programs on green infrastructure (2).
To address existing knowledge gaps, a number of research and practice projects are focusing their efforts
on generating and centralising targeted information for easier access and increased uptake by various user
groups. Areas of focus include: identifying available types of NBS; producing targeted guidance; developing
methods for evaluating NBS impacts and benefits; generating digital knowledge platforms; supporting
events for discussion and exchange; and, translating scientific evidence into policy briefings. These
resources can be utilised by city planners, practitioners, NGOs or other interested stakeholders to promote
improved planning, implementation and monitoring of NBS. Several resources of key importance are listed
below.

EKLIPSE (10) and ThinkNature Task Force on impact evaluation: Measurement of NBS
benefits and effectiveness
These efforts to improve information flows between policy makers, experts, businesses and society on best-
practice solutions, and previous mistakes and lessons learned, are largely taking place on a higher (often
European) scale, but they also need to be systematised at the city level for maximum impact (11). In
particular, as NBS aim to achieve multiple benefits such as increased climate adaption, improved human
well-being and socially inclusive growth, the perspectives, experience and knowledge of various experts
and citizens groups have to be included in a holistic planning approach (8,12). Hence, city planners, urban
designers and parks managers might need to identify ways to involve external experts or a public exchange
of ideas as concrete steps within the design process. The promotion of successfully realised pioneer
projects and official certification can also help further increase the general awareness of NBS.6
Even with the best generic technical guides and information at hand, dealing with dynamic natural systems
implies the presence of unexpected site-specific local constraints. For instance, the effective installation of
sustainable drainage systems depends on the adequate soil type while guidelines and regulation for green
roofs should recognise the implications of local climatic conditions (4,13). In the same vein, other region-
specific framework conditions, like city structures or regulatory laws etc., might also influence the impact of
NBS. Hence, evidence building should always be based on locally sourced knowledge.
2.2. Governance of multifunctional green infrastructure
NBS emphasise the potential positive interaction of environmental, economic and social systems. In doing
so, they can deliver multiple benefits. For example, multi-functionality green spaces can support adaptation
to climate change while also being used for sports and recreations, serve as a place for local
distinctiveness, increase the aesthetic appeal of a neighborhood, and provide a sense of community (14).
However, such multifunctionality requires that appropriate governance structures are in place. This can be
a challenge for local authorities, as they have traditionally worked in departmental structures, yet NBS are
relevant for various departments simultaneously (e.g. planning, economic development, environment,
transport, and innovation) (4). As a result, single objective grey or green infrastructure solutions (so-called
‘silo-solutions’), which only meet the objectives of one single department, are often pursued over hybrid
(green-grey infrastructure) or multifunctional green solutions (5). Further tensions can arise in the
coordination between local, regional and national governments when they have different political ambitions
and the legal responsibilities between governance and management of NBS are separated (4,15).
Effective governance is likely to require authorities to break out of their traditional structures and collaborate
on cross-departmental planning strategies, asset management, and budget delegation (9,16). Clear
responsibilities and coordination across departments are needed to help foster successful collaboration (4).
The integration of independent external experts (e.g. from universities) can support collaboration as they
can certify the usefulness of cross-departmental solutions and mediate between departments (1,9). Ideally,
city governments should create new, horizontal positions in both their political and management structures
to achieve coordination and policy integration, as has been the case in the city of Genk (17).

2.3. Balancing trade-offs while delivering multiple goals
NBS try to deliver environmental, social and economic goals simultaneously. An additional challenge of
planning and implementing NBS is taking account of and addressing the potentially conflicting interests of
the stakeholder groups involved in decision-making who may have a specific focus on only one of these
goals
One possible solution is to encourage the active participation of the widest range stakeholders early in the
process (see section 2.4) to increase the understanding of the diversity of goals and priorities of interested
parties (5,12). Furthermore, the planning stage of NBS requires the identification of both the possible
synergies and conflicts between various economic, environmental, and societal interests and the potential
trade-offs that might need to be negotiated; this information must be clearly communicated amongst all the
stakeholders involved (14,18). Spatial mapping and assessment tools can be used to locate, identify and
quantify the different functions and services of green infrastructure within a city (9). For instance, such a
tool has been developed and applied in Liverpool7 and further adapted in Adelaide (19). In London an
interactive Green Infrastructure Focus Map has been developed and will be published by the end of 2018.
In some cases, hybrid solutions which include elements of both green and grey infrastructure can be helpful
to address multiple priorities while limiting trade-offs as they are based on existing infrastructure (9).
2.4. Citizen involvement
Better delivery of the social, economic and environmental benefits of NBS will only occur when the interests
of the public are fundamentally incorporated in the planning process. This requires that user groups and
other interested stakeholders are consulted and ideally involved in the planning, implementation and
monitoring processes, which can also serve to build personal connection with the project and a sense of
community ownership. However, achieving inclusive and active participation can present a challenge.
Public participation can be fostered by: maximizing the flow of targeted information to stakeholder groups
and organizing consultations, workshops and opportunities for feedback (2) and communicating the multi-
functionality of NBS (20,21) to increase awareness and support. Volunteers can also be invited to help in
the implementation and monitoring processes (21,22,23) or in maintenance activities (e.g. through formal
contracts between the city and NGOs)(24). In some cases, citizen participation might be limited by the value
they attach to public green spaces or NBS, which might depend on their socio-economic or cultural
background or influenced by their experience with other green spaces (15). 8 Here, designing NBS
interventions that can cover both private initiatives (e.g. installing private green roofs and improving the
ecological function of private gardens) and collective action (e.g. urban farming or improving opportunities
for children’s play) can animate a community across all income levels (28). In general, some evidence
suggests that NBS focusing on the protection of ecosystems and wildlife have been especially successful
in attracting public engagement (14,29).
7 www.gift-t.eu/manual/mapping-tools/gi-mapping 8 Women and the elderly show higher valuation (25), richer people and immigrants show lower valuation (26). Minorities, lower-income and elder people tend to have lower access to green spaces (14,27).

2.5. Social inclusion
An active civic role in the NBS planning does not alone guarantee social inclusive outcomes, as people
with higher incomes or social status can dominate the planning processes. The interests of groups like
women, ethnic minorities or disabled people might not be given equal consideration and some citizens
might not have access to standard participation tools (11,30).
In an effort to combat these potential downfalls in planning, groups with less power need to be identified
and targeted through the implementation of inclusive participation programs. In Aarhus, for instance, young
people from different ethnic backgrounds have been employed as leisure time workers to inform the diverse
population of the participative possibilities in the planning of NBS and the decision making (9,30). Moreover,
realized NBS such as urban parks can become places for interaction between people with different
socioeconomic backgrounds and thus help to further foster social cohesion in the long run (31).
2.6. Public acceptance
Lack of public support, beyond an unwillingness to participate in planning processes, can also be an
impediment. Such resistance can be motivated by an underappreciation of environmental benefits, fear of
heightened costs for the implementation and maintenance of green spaces and distrust in the publicly
announced costs and benefits, or the fear of rising housing prices (a product of so-called ‘eco-’ or ‘green
gentrification’). As a result, the risk of vandalism can be a problem for the successful implementation of
NBS (7).
Consequently, NBS must be sensitive to their location and to the social dynamics they may inadvertently
trigger (32,33). Regarding gentrification fears specifically, expected impacts on property values can be
estimated9 during the conceptualization and planning process, and the local population can be actively
involved to support processes which can achieve neighborhood stabilization (33). Social policy experts and
economists should therefore be included in the planning of NBS. Environmental education and capacity
building linked to the project can serve to inform the public about the benefits of NBS while offering
opportunities for actively involve children and the youth on the project site can also increase community
support (2). From a technical perspective, landscape architects should be involved in the co-design of NBS
to combine ecological functionality with aesthetic principles as this increases acceptance and reduces
vandalism (6,28).
2.7. Political support
Implementation of NBS is often hindered by a lack of continued political support. Most benefits from NBS
are ‘public goods’ and the economic benefits of these, plus the non-economic benefits (such as aesthetics)
are underappreciated by politicians, policy-makers and the wider public (21,35). Moreover, the process of
urban planning and regeneration takes place over a long time span and positive results, especially social
and economic benefits such as improvements in public health often only emerge in the long-term. NBS
suffer therefore from politically-driven short-term action and decision-making cycles (4). Private entities can

be more agile; however, they also have to respond to the policy-frameworks and are reluctant to act until
the policy direction is clear and consistent.10 Furthermore, environmental and heritage protection laws, and
building regulations and planning permits can limit the number of potential opportunities for NBS
(7,28,36,37) that may already limited be constrained by existing competing land-uses and utility
infrastructure such as water pipes, electric wires and underground structures (4,30).
It is crucial to integrate and consider NBS in every planning tool, adjusted to the details needed and to
answer to the step in decision making. It should be considered as part of the strategy, going beyond the
relevance of greenery on traditional urban regeneration processes, that otherwise is only considered at the
very last step of the process.11 The economic value of NBS can be revealed or made more transparent
through natural capital accounting which has been done in London.12 Subsidies to install NBS solutions in
private houses or buildings can mitigate the long planning and amortization process. 13 Green-grey
integration can be a remedy for competing land-use, while planning laws e.g. for habitat preservation and
compensatory measures for unsealing make greening policies mandatory (30).
2.8. Financial support
Budget constraints are also a frequent barrier for NBS projects. Long-term financial plans have to be put in
place for the implementation period as well as for later maintenance of the site (2,11,12). Where
maintenance costs count as discretionary services, they are especially vulnerable to budget cuts (4). The
cost of enhancement (e.g. retrofitting a public park to improve its functionality) can also reduce political and
civic support if the existing space is perceived to provide basic functions such as recreation and play.
Furthermore, because NBS ae still novel interventions, financial commitment is also needed for the
monitoring and evaluation which increases the apparent cost of the project (2,11).
In anticipation of possible budget cuts, NBS can be planned in a way that the technical specifications can
be adapted to the budget (e.g. number of the trees, green roofs, surface covered) while the quality of the
project as such is not influenced (4). A coherent and consistent planning policy or regulatory regime can
help to ensure a more stable programme of financial support by providing certainty about what is required
from particular actors (e.g, developers). The integration of ecological indicators in fiscal transfers between
municipalities can incentivize the implementation of green infrastructure (22). Public-private partnerships
channel private capital into NBS both at the implementation and maintenance stage and allow for efficient
risk and benefit sharing (2,21,22).14 Green barters, where businesses, such as cafés located in parks,
commit themselves to maintenance activities in exchange for monetary gains from green spaces, are
another solution (38). Moreover, NBS can strategically be planned and delivered on third party land, where
the owner values the intervention and accepts the maintenance costs over the long-term (4). Citizen
involvement in maintenance brings in people with knowledge about the individual site and local population.
Citizen-led initiatives might need technical support by a local authority and flexible application of municipal
regulations, but might also be eligible for external government money denied to the municipality (4,39).

Likewise, volunteers and ‘citizen-scientists’ can participate in monitoring activities and thus limit monitoring
costs.
2.9. Challenges for Evaluation
NBS aim to improve the environment while providing sustainable economic growth, improved health, social
cohesion and security for the population, amongst other benefits. Monitoring and evaluation of these
impacts is needed to assess the effectiveness of specific interventions, increase comparability across
different NBS, improve NBS design into the future, and create a robust evidence base which will help to
mainstream NBS as an alternative or complement to traditional grey solutions. However, while efforts have
and are being made to generate an overarching NBS evaluation framework (e.g. EKLIPSE (10), MAES
(40), UNALAB, Naturvation), there is currently no commonly accepted and easily implemented monitoring
framework.
Efforts for a common indicator base are being pursued on the European level via the ThinkNature taskforce
“NBS Impact Evaluation Framework version 2.0”. One major challenge in this process is the aspect of
measuring intangible values. Better indicators for sustainability and social outcomes are needed (12). Due
to the concerns regarding the right measuring approach, multiple methods might be applied (41). However,
if results are not robust across approaches, trust in the results might be weakened. The combination of high
resolution geographic and land-use data with preferences and behavioral data of people can provide helpful
insights (15). More generally, cities can work with available city level data and – where possible – conduct
targeted studies focusing on the e.g. socio-economic value produced by NBS interventions. It is important
to gather baseline data before the intervention and then conduct monitoring after the implementation is
completed.
2.10. Challenges for upscaling
For the systematic replication of NBS on a broader base and scale, the barriers described above apply to
their co-design and implementation. Furthermore, planning for the upscaling of NBS is hampered by the
lack of quantitative evidence of upscaling successes (42). Upscaling also increases the pressure on
governance structures as different actors and departments have to cooperate (4,11) and the knowledge,
practices and technologies have to be transformed to and be made applicable at a larger scale (43).
Moreover, the ownership and use of land will become a larger barrier (14) as land can be overwhelmingly
owned by actors who put their financial interests over environmental goals (4).
Guidance documents like the one on sustainable drainage systems by the London Borough of Tower
Hamlets (44) and municipal strategies that mainstream NBS can help to institutionalize the process (45).
For this, multiple actors and their interests have to be included: city objectives and policies, stakeholder
views, and the expected benefits from NBS have to be aligned with spatial plans, business models &
financing mechanisms and delivery & maintenance mechanism, while monitoring and evaluation feed back
into the planning.15 Regulatory measures such as mandatory constructions of green roofs on new buildings
(e.g. in Copenhagen and Toronto) foster the proliferation of this NBS. Financial incentives for the building

of green spaces such as subsidies for green roofs, storm water fees and blue-green factors give incentives
for the installation of green infrastructure (21,46,47) Strategic collaboration with business incubators can
attract and nurture promising start-ups (43). Finally, the conflict between place specificity and replicability
requires the design of marketable NBS to be flexible in order to adapt to specific needs (43).
3. Concluding remarks
The potential positive interactions of environmental, economic and social systems lie at the heart of NBS
and have to be kept in mind at all stages of co-creation, implementation, evaluation and upscaling of the
interventions. CLEVER Cities can draw on the experiences of past and ongoing projects in the field of
nature-based solutions and green regeneration of cities in general. In co-designing, implementing and
evaluating CLEVER Frontrunner and Fellow Cities will add to the knowledge base on NBS. This will further
help to mainstream the concept of NBS within city governments which is essential to transform NBS beyond
single interventions into city-wide planning processes.

Annex 2 – Overview of key barriers and solutions
Barrier Potential solutions
Knowledge gaps Integrate local stakeholders and experts. Use the existing knowledge base. Promote successful pioneer projects.
Governance of multifunctional green infrastructure
Collaborate on cross-sectoral planning and decision making. Create new cross-sectoral positions. Use external experts as mediators.
Balancing trade-offs while delivering multiple goals
Involve diverse stakeholders. Apply spatial mapping and assessment tools. Integrate grey and green infrastructure.
Citizen involvement Communicate benefits of NBS. Engage volunteers. Combine private and collective action.
Social inclusion Apply targeted participation programmes for less powerful residents. Encourage the interaction of people with different socioeconomic background.
Public acceptance Be aware of the social dynamics of greening strategies. Foster environmental education. Involve landscape architects.
Political support Integrate NBS in planning tools. Adopt planning laws for NBS proliferation.
Financial support Make NBS resilient to budget cuts. Impose regulatory instruments. Apply public-private-partnerships. Rely on citizen-led initiatives.
Challenges for evaluation Engage with the ThinkNature taskforce “NBS Impact Evaluation Framework version 2.0”. Combine geographic and land-use data with preference data.
Challenges for upscaling
Adapt and/or compile guidance documents. Institutionalize the NBS process. Consider regulatory measures and financial incentives. Support start-ups.
